Early (30 Days) Outcomes In Coronary Artery Bypass Grafting Patients With Previous Coronary Stent

Abstract

Background: Coronary artery bypass graft (CABG) operation is commonly performed to improve symptoms and outcomes in cases with complex coronary artery disease (CAD). Number of cases with a prior history of percutaneous coronary intervention recommended for a CABG procedure has consistently risen in recent years.

Results: Intraoperatively, 91.2% of patients had on-pump coronary artery bypass grafting (CABG), with mean cardiopulmonary bypass (CPB) and cross-clamp times of 126.4±44.9 and 94.03±35.2 minutes, respectively. 52.9% required inotropic support, and 5.9% had intra-aortic balloon pump (IABP) placement, with insignificant variations among groups (p > 0.05). Postoperatively, 7.8% of patients underwent re-exploration for bleeding, 2.9% experienced myocardial infarction (MI), 7.8% developed arrhythmia, and 2% died. Superficial and deep sternal infections occurred in 3.9%, with a mean hospital stay of 5.85±2.5 days, demonstrating insignificant variations among groups (p>0.05).

Conclusions: Insignificant variations have been found in demographics, surgical parameters, or complications between groups.
